Here are the results, The 1 ppm moly really is amazing based on what others
have said about the add pack. It will be interesting to see how those levels
track as we go along. You can compare the oxi and nit to other scales by
dividing them by 2. 80 = 40 or so. the only area of concern to me is the
lead at 19 ppm. Hard driving generates this and is common with this 5.7
engine. Vis is solidly 30w and TBN is good at 8. I recommend sticking with
it for some time to see if wear drops even lower. This is a very good result
as far as wear.
